R&D tax credit, roughly what it's worth
The federal credit under the Alternative Simplified Credit method is 14% of your qualified research spend above a base, or 6% if you've never claimed before. Put your numbers in for a ballpark. It's an estimate to tell you whether a study is worth a call, not a figure to file.
Estimated federal credit
What this estimate leaves out
This is the gross federal ASC credit only. Three things change the number you actually keep, and all of them depend on your situation, so they belong with your CPA, not in a browser:
- The Section 280C election, which trades a smaller credit for keeping your deduction. Often worth it.
- The payroll-tax offset, which lets a qualified small business use up to $500,000 of the credit against payroll taxes instead of income tax, useful if you're pre-profit.
- State credits, which many states stack on top of the federal one.
Rates: 26 U.S.C. 41(c)(5) (ASC: 14% over base, 6% first-time), verified July 2026. Estimate only, not tax advice.

What counts as a qualified expense
The credit isn't only for lab coats. Wages for the people doing and supervising the work, supplies consumed in it, and 65% of contract research all count, as long as the work meets the four-part test. Getting these inputs right is what moves the number.


Who can actually use it
A profitable company takes the credit against income tax. A pre-profit startup can apply up to $500,000 against payroll taxes instead, which is why the tool is useful even before you owe income tax.
